Based on a review of the literature, reference intervals for water buffalo (Bubalus bubalis) serum biochemistry and haematology have not previously been published. The current study was done to establish reference intervals for water buffalo heifers. The International Federation of Clinical Chemistry stated that at least 120 values are necessary to obtain(More)
The aim of this study was to investigate uterine torsion in buffaloes, examine factors influencing the outcome of the disease, and to characterize the related alterations in blood constituents. A total of 126 buffaloes with uterine torsion were examined for stage of gestation, duration, degree, site and direction of torsion, as well as the location of the(More)
The goal of this study was to assess if oxidative stress, as measured by alterations in the concentrations of antioxidant enzymes in the liver and erythrocytes of cattle, could be induced following dl-ethionine administration. Whole blood, serum and liver biopsy samples were collected 0, 4, 7 and 10 days after intra-peritoneal ethionine administration to(More)
A total of 46 cattle, including 25 as control, 16 with glycogen degeneration and 5 with severe fatty degeneration were studied. Whole blood and liver tissue specimens were used to measure glutathione peroxidase (GSH-Px) and Glucose-6-Phosphate Dehydrogenase (G6PD) activities. The present study determined the value of these parameters in diagnosing glycogen(More)
The aim of the present study was to determine the level of serum liver enzymes, triglyceride and some metabolites in cows with or without difficulties during parturition. The second goal was to compare between the possible effects of caesarian section and fetotomy on these parameters. A total number of 24 native breed cows at full term were included in this(More)
The goal of the present study was to measure the total glutathione level and glutathione reductase activity in bovine erythrocytes and liver biopsy. Five cows were injected intraperitoneally with DL-ethionine (12.5 mg/kg B.W.), and two control cows were injected with normal saline (0.9% NaCl). Ultrasonography guided liver biopsy, and blood samples were(More)
The goal of the current paper is to explore the role of liver biopsy as a tool in detection of hepatic oxidative stress, with brief notes on different types of free radicals, antioxidants, hepatic and blood oxidative stress, and lipid peroxidation. Hepatic oxidative stress was investigated for many years in human and animals, but most of the studies(More)
This study was performed for the purpose of investigating the prevalence and the species composition of Sarcocystis spp. in buffaloes in Assiut province, Egypt. Macroscopically we reported the infection of buffaloes with Sarcocystis fusiformis, while microscopically three Sarcocystis species (Sarcocystis cruzi, Sarcocystis levinei and Sarcocystis hominis)(More)
A total of 60 cattle were examined for the presence of pathological liver lesions. The liver lesions were classified as glycogen degeneration, liver abscess, sawdust liver and fatty degeneration. The value of serum adenosine deaminase (ADA) activity was investigated as a pilot study for diagnosing liver diseases in cattle. Serum ADA activity was(More)
In the asexual stages, Toxoplasma gondii stage converts between acute phase rapidly replicating tachyzoites and chronic phase slowly dividing bradyzoites. Correspondingly, T. gondii differentially expresses two distinct genes and isoforms of the lactate dehydrogenase enzyme, expressing LDH1 exclusively in the tachyzoite stage and LDH2 preferentially in the(More)
